Sperm also has a 'switch' that helps to turn on and off

Scientists have discovered that sperm switches that work on and off can work to prevent sperm from reaching the egg. This can be a safe and effective contraceptive on the body of both men and women.

Scientists have discovered that the "sperm switch" that operates under "on - off" may work to prevent "swimming" sperm from meeting eggs. This can be a safe and effective contraceptive on the body of both men and women.

Scientists may have found a power switch that "turns on" off sperm activity by detecting the ion flow inside the sperm.

The sperms only have a length of 0.005mm will have to go through the cervix, wriggle into the fallopian tube, pass the distance 24,000 times their body length to reach the egg.

How does sperm enter the egg?

Upon arrival, the sperm will have to put all the energy into its tail, straight and decisively like a drill to pierce through a 0.3mm-thick transparent film that covers the outside of the egg. This action is called "internal force push" by scientists.

Sperm must rely on a large amount of Catsper, a type of ion that can absorb calcium in the human body for more energy to perform an "internal force push" near the egg.

Researchers at UC Berkeley have found more than 50 chemical compounds that can be closely linked to Catsper, and neutralize the activity of this ion.

Lupeol and pristimerin are two of 50 compounds that can prevent calcium precipitation - the energy needed for sperm. They can prevent fertilization and embryo formation at any time and are used as a timely contraceptive, which is 10 times more effective than commercial contraceptives. The current. These compounds can be found in plants such as grapes, mangoes, dandelions, aloe vera and angiosperms.

Lupeol compounds are abundant in grapes.

The researchers obtained this result from tests on human sperm in laboratory conditions. They will conduct experiments on primates to see how long this new method can neutralize sperm, in doses.

The team hopes to both produce oral medicines for men and women, and be able to perform human body transplants later this year.
